The sun provides light energy which plants use to convert in to chemical energy through photosynthesis. Nutrients from the soil also assist in growth of plants. Animals rely completely on these green plants for their energy. Green plants produce chemical energy (food energy).
The energy stored in plants is classified as potential energy because they convert light energy into chemical potential energy stored in glucose.
the green pigment in plants that traps radiant energy from the sun is glucose
Because of Chlorophyll present in it
The green colouring comes from chlorophyll , the same pigment that is found in foliage. a green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis. Its molecule contains a magnesium atom held in a porphyrin ring.

Due to the presence of chlorophyll plants are green in color.
Chlorophyll in plants does not absorb green light as they reflect this color. That is why plants are, generally, green as they reflect green light and absorb other wavelengths of light.
That's vey simple, they absorb every other colour. It has to do with the energetic value of the light at different waves, so for green plants, green light gives them least. The reason green plants reflect green light is also simple. Photosynthetic substances like chlorophyll require different amounts of energy, and reflect/absorb different wavelengths of light. At certain temperatures, plants can only maintain carotenoids, which often reflect more reds and yellows (this is why tree leaves change color in the fall), and at more ideal temperatures, plants are able to absorb enough energy to produce chlorophyll. A plant's color is completely dependent on its photoabsorbtive pigments. This is also why plants that are locked in a closet will turn white, but still live for a while: they devote their energy to tasks besides producing photoabsorbants, since there are few photons to absorb.
The chlorophyll in plants actually doesn't absorb green pigment; it reflects it, which is why chlorophyll is green.
Different plants absorb different colors. Even different parts of plants absorb different colors. The color you see the plant as is the color being reflected rather than absorbed by the plant.
